.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH DESCRIPTION
This package provides a class for accessing geocoding services which implement
the \fINominatim\fR interface (see \fBReferences\fR)
.SH API
.TP
\fB::map::geocode::nominatim\fR \fIrequestor\fR ?\fB-baseurl\fR \fIurl\fR? ?\fB-callback\fR \fIcallback\fR? ?\fB-error\fR \fIerror callback\fR?
Creates a geocoding request object \fIrequestor\fR, which will send its requests to
the \fINominatim\fR server\&.
.sp
The result of the command is \fIname\fR\&.
.PP
.SS OPTIONS
.TP
\fB-baseurl\fR \fIurl\fR
The base URL of the \fINominatim\fR service\&. Default value is \fIOpenStreetMap's\fR service at
\fIhttp://nominatim\&.openstreetmap\&.org/search\fR A possible free alternative is at
\fIhttp://open\&.mapquestapi\&.com//nominatim/v1/search\fR
.TP
\fB-callback\fR \fIcmdprefix\fR
A command prefix to be invoked when search result become available\&.
The default setting, active when nothing was specified on object creation, is to print
the \fIresult\fR (see below) to \fIstdout\fR\&. The result of the command prefix is
ignored\&. Errors thrown by the command prefix are caught and cause the invokation of
the error callback (see option \fB-error\fR below), with the error message as argument\&.
.sp
The signature of the command prefix is:
.RS
.TP
\fB$cmdprefix\fR \fIresult\fR
The \fIresult\fR is a list of dictionaries, containing one item per hit\&.
Each dictionary will have the following entries:
.RS
.TP
place_id
The place ID (FIXME: what's this?)
.TP
licence
The data licence string
.TP
osm_type
The OSM type of the location
.TP
osm_id
FIXME
.TP
boundingbox
The coordinates of the bounding box (min and max latitude, min and max longitude)
.TP
lat
The location's latitude
.TP
lon
The location's longitude
.TP
display_name
the location's human readable name

\fB-error\fR \fIcmdprefix\fR
A command prefix to be invoked when encountering errors\&. Typically these are HTTP errors\&.
The default setting, active when nothing was specified on object creation, is to print
the \fIerrorstring\fR (see below) to \fIstderr\fR\&. The result of the command prefix is
ignored\&. Errors thrown by the command prefix are passed to higher levels\&.

.SS METHODS
.TP
\fIrequestor\fR \fBsearch\fR \fIquery\fR
This method returns a list of dictionaries, one item per hit for the specified \fIquery\fR\&.
